60 minutes..cornelia rau, page-29

re: 60 minutes..cornelia rau -yak Yak, what makes me curious is that Cornelia has been pigeon-holed as having schitzo.
Now, if this is correct, this should have been manifested by the time Cornelia was in her early 20's.
I am assuming that she didnt demonstrate any bizzarre behaviour as a stewardess and she didnt have it then, so how would you explain this?

cheers
